• benign
  • Urinary retention, which is a common complication of benign prostatic hyperplasia (BPH), though it can also be caused by other types of urinary tract obstruction, nerve dysfunction, tethered spinal cord syndrome, constipation, infection and certain medications. (wikipedia.org)
  • tumours
  • Neuro-oncology deals with the study of brain and spinal cord tumours, which is usually life threatening. (omicsonline.org)
  • Intradural tumours can be classified as intramedullary (within the spinal parenchyma) or extramedullary (within the dura, but outside the spinal parenchyma). (wikipedia.org)
  • Interventional oncology has developed to a separate pillar of modern oncology and it employs X-ray, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to help guide miniaturized instruments (e.g. biopsy needles, ablation electrodes, intravascular catheters) to allow targeted and precise treatment of solid tumours (also known as neoplasms) located in various organs of the human body, including but not limited to the liver, kidneys, lungs, and bones. (wikipedia.org)
  • Brain
  • In these cases, untreated survival usually amounts to only a few months, and survival with current radiation and chemotherapy treatments may extend that time from around a year to a year and a half, possibly two or more, depending on the patient's condition, immune function, treatments used, and the specific type of malignant brain neoplasm. (wikipedia.org)
  • They may occur anywhere in the brain, or even in the spinal cord, but are most commonly found in the cerebral hemispheres. (wikipedia.org)
  • As the alternative name of "diffuse astrocytoma" implies, the outline of the tumour is not clearly visible in scans, because the borders of the neoplasm tend to send out tiny microscopic fibrillary tentacles that spread into the surrounding brain tissue. (wikipedia.org)
  • Prostate Cancer
  • Transitional cell carcinoma (bladder cancer), renal cell carcinoma (kidney cancer), and prostate cancer are examples of neoplasms affecting the urinary system. (wikipedia.org)
  • radiation
  • Radiation is usually delivered to the involved segment in the spinal cord as well as to the uninvolved segment above and below the involved segment. (wikipedia.org)
  • Astrocytoma
  • Poorly defined margins may be more suggestive of astrocytoma, while a central location in the spinal cord, hemorrhage, and hemosiderin staining are often seen with ependymoma. (wikipedia.org)
  • segment
  • Routine imaging of the spinal segment. (clinicaltrials.gov)
  • Evaluation with Magnetic Resonance (MR) most commonly demonstrates a circumscribed solid or mixed solid and cystic mass spanning a long segment of the cord with hypointense T1 signal and hyperintense T2 signal in the solid component. (wikipedia.org)
  • tumoral
  • These do not affect the tumoral mass itself, but tend to reduce the inflammatory reaction around it, and thus decrease the overall volume of the mass impinging on the spinal cord. (wikipedia.org)
  • surgical
  • I. To perform a small pilot study that will demonstrate the feasibility of neurosurgical spinal procedures using the da Vinci surgical robot. (clinicaltrials.gov)
  • disease
  • Adjuvant chemotherapy is also typically reserved for anaplastic ganglioglioma, but has been used anecdotally in partially resected low grade spinal cord gangliogliomas which show evidence of disease progression. (wikipedia.org)
  • rare
  • Tumefactive demyelination of the spinal cord is rare but it has been reported Damage is not confined to the demyelinating area. (wikipedia.org)
